Benefits of technology
[0006]The present invention provides a method of manufacturing corrugated board using acid treated zeolite to maintain the freshness of various natural food products for an extended period of time.
[0008]In view of the above, it can be seen that a significant advantage of this invention is that removing the filth or dirt by pre-processing natural zeolites with concentrated acid maximizes the freshness of food products stored in the corrugated box.
Problems solved by technology
However, in reality, the pores in the natural zeolite are mostly filled with filth or dirt, thereby closing the pores, making it impossible to exhibit high absorption and cation exchange capability.

Embodiment Construction
[0015]Illustrated in FIG. 1 is a flow chart showing the process of manufacturing the corrugated board using the acid treated zeolite, according to the present invention. The corrugated board manufacturing process is comprised of zeolite acid treatment process 100, adhesive making process 110, adhesive applying process 120, and board assembling process 130.
[0016]FIG. 2 shows a flow chart illustrating the process of the zeolite acid treatment, according to the present invention. The process includes the following steps: crushing zeolite into small particles 210, washing the zeolite with water 220, draining the water from the zeolite 230, mixing the zeolite with concentrated acid 240, draining the acid from the zeolite 250, rinsing the acid treated zeolite with water 260, drying the acid treated zeolite 270, and grinding the dried acid treated zeolite into smaller particles 280.
[0017]The zeolite being used in the present invention is natural state zeolite. At step 210, the zeolite is c...

Abstract
A method of manufacturing corrugated board uses acid treated zeolite to maintain the freshness of various natural food products for an extended period of time. The method of manufacturing corrugated board using acid treated zeolite comprises a zeolite acid treating process, an adhesive making process, an adhesive applying process, and a board assembling process wherein a corrugated sheet is layered between an upper liner sheet and a lower liner sheet which is then bonded to form a corrugated board. A significant advantage of this invention is that removing the filth or dirt by pre-processing the zeolite with acid treatment maximizes the freshness of food products stored in the corrugated box.
Description
BACKGROUND OF THE INVENTION[0001]The present invention generally relates to a method of manufacturing corrugated board. More particularly, this invention relates to a method of manufacturing corrugated board using acid treated zeolite to maintain the freshness of various natural food products for an extended period of time.[0002]Zeolites are commonly known for having a porous structure that can be readily dehydrated and rehydrated, and are used as cation exchangers and molecular sieves. There have been proposed methods of manufacturing corrugated boards using cornstarch and the zeolites for extended freshness to utilize the porous structure.[0003]However, in reality, the pores in the natural zeolite are mostly filled with filth or dirt, thereby closing the pores, making it impossible to exhibit high absorption and cation exchange capability.[0004]In addition, conventional techniques of using the adhesive for the corrugated board have been problematic because the particle of the zeol...
